一类含输入时滞非线性系统的干扰观测器控制
Disturbance Observer Based Control for a Class of Nonlinear Systems with Input Time-delay
摘要
Abstract
Disturbance-observer-based control (DOBC) has been considered as an effective disturbance rejection scheme in applications. However, if the control input and disturbance cannot enter the control channel at the same time, it will be difficult to estimate and compensate the exogenous signals in real time. A compound DOBC method, consisting of a disturbance observer, disturbance prediction and a feedback regulation part, is thus developed. One novel feature of the proposed method is that the merits of DOBC can be inherited for a class of nonlinear systems with input time-delay. Moreover, stability analysis for both the dynamic prediction error system and the composite closed-loop system is provided by designing an auxiliary observer.关键词
